Often times when patients complain about chest discomforts and pain and , the occurrence of aneurysm(s) is are suspected, it . It is difficult to pinpoint the exact location of the aneurysm. Hence MRI and CT scan are the most frequently used tools to detect the presence and location of aneurysms. In this scenario, the test location is locations are often broadly defined as the subject's chest, abdominal cavity or the whole - body. The specific location(s) where aneurysms are found are actually locational qualifiers for the resultsidentified/found should be mapped to result location, not test.

From the CV-imaging project we also encountered use-cases where we need sub-loc LOC variables to help to further specify the free-text, detailed, more granular locations where a test is performed. Those These values are indeed clinically relevant location information that should NOT be pre-coordinated into the TEST itself, but are also inappropriate for LOC.

Row 1: | Shows the cross-sectional diameter of the left ventricle at end ventricular diastole, measured along the minor axis and specifically at the location of the high papillary muscle. The further anatomical details more granular, free-text anatomical description at which the measurement is set and performed is represented by the CVLOCDTL CVTLODTL NSV. |

Row 2: | Shows the cross-sectional diameter of the right ventricle at end ventricular diastole, measured along the minor axis and specifically at just below the tricuspid valve. The further anatomical details more granular, free-text anatomical description at which the measurement is set and performed is represented by the CVLOCDTL CVTLODTL NSV. |
